Description

Pressing non-girdle-belt zirconium oxide grinding medium ball die

Technical Field

The utility model belongs to the relevant equipment field of mechanical pressure ball, concretely relates to suppression does not have clitellum zirconia and grinds medium ball mould.

Background

When the spherical blank is made from powder, a series of processes such as material preparation, forming, sintering, shaping, polishing, screening and the like are needed in the mechanical ball pressing production process, the forming is used as an initial process, the forming has great influence on the subsequent process, when the existing spherical blank is produced by mechanical ball pressing, an upper hemispherical die and a lower hemispherical die which are shown in figure 1 are generally adopted, balls are formed by pressing, the ball manufacturing efficiency of the die is higher, but a raised annular belt is inevitably arranged in the middle part of the ball pressed by the die, because the ball forming cavity is divided into two regular hemispheres, the side wall of the die cavity has certain thickness, no matter the thickness is, the thickness is thick, a horizontal plane is formed, when the prepared powder is put into the die, a small amount of powder is scattered on the horizontal plane, the distance between the two hemispheres can be infinitely close to each other in the pressing process, but the powder cannot be pressed out, the spheres extruded by the sphere die in fig. 1 must therefore have a ring belt. In order to ensure the roundness of the ball, the subsequent shaping and ring removing treatment needs to be carried out, and extra labor is required.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a spherical mould of no clitellum of suppression is provided to the not enough of clitellum that exists to current mould pressure ball.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a pressing non-girdle zirconia medium grinding ball die comprises a hemispherical upper female die with a hole at the top end and a hemispherical lower female die with a hole at the bottom end; an upper punch is arranged at the top hole of the upper female die and forms a complete hemisphere with the upper female die, a lower punch is arranged at the bottom hole of the lower female die and forms a complete hemisphere with the lower female die.

The upper part of the upper female die is provided with an upper guide hole module of an upper punch, and the lower part of the lower female die is provided with a lower guide hole module of a lower punch.

The utility model has the advantages that: through adopting foraminiferous hemispherical female die in top and the foraminiferous hemispherical female die down in bottom, go up the stamping and form complete hemisphere type with last female die cooperation, lower female die and lower die punch cooperation form complete hemisphere, clitellum when avoiding mechanical pressing between the stamping appears, can save the plastic technology, and the ball circularity is good to save the labour, raise the efficiency, reduce cost.

Wherein 1 is an upper punch, 2 is an upper guide hole module, 3 is an upper female die, 4 is a lower female die, 5 is a lower guide hole module, and 6 is a lower punch.

Detailed Description

As shown in FIG. 2, a pressing ring-free zirconia milling medium ball die comprises a hemispherical upper female die 3 with a hole at the top end and a hemispherical lower female die 4 with a hole at the bottom end; an upper punch 1 is arranged at the top hole of the upper female die 3, the upper punch 1 and the upper female die 3 form a complete hemisphere, a lower punch 6 is arranged at the bottom hole of the lower female die 4, and the lower punch 6 and the lower female die 4 form a complete hemisphere.

The upper part of the upper female die 3 is provided with an upper guide hole die block 2 for punching an upper die, and the lower part of the lower female die 4 is provided with a lower guide hole die block 5 for punching a lower die.

The upper punch 1 can move up and down in the guide hole of the upper guide hole module 2 and the upper female die 3; the lower punch 6 can move up and down in the lower guide hole module 5 and the lower female die 4; the upper guide hole module 2 and the lower guide hole module 5 are respectively matched with an upper punch and a lower punch, have the function of fixed guiding, and can reduce the processing length of the upper female die 3 and the lower female die 4, and reduce the processing cost and difficulty of the die.

When in use, the lower female die 4 is fixed on an equipment table, the upper female die 3 is placed on the lower female die 4, the lower female die 4 and the lower guide hole module 5 are matched, the lower punch 6 is inserted into a hole of the lower female die 4, the insertion depth is adjusted according to the using amount, after the required powder amount is added through a hole at the top of the upper female die 3, the formation of the upper punch 3 and the lower punch 4 is adjusted through pressing equipment, and powder is pressed into balls; after the ball is formed, the upper female die 3 moves upwards, the upper punch 1 moves upwards, and the ball can be taken out. The use of the die can realize automatic ball pressing through automatic pressing configuration, automatic feeding configuration and automatic ball discharging configuration of the pressing equipment. Compared with the upper and lower punches in the prior art, the cross sectional area of the upper and lower punches in the utility model is smaller, and balls can be pressed out by less force in the pressing process, thereby saving energy sources compared with the prior art; the method has the advantages that the ring belt is not arranged, the shaping process can be omitted in the subsequent processing process of the zirconium oxide grinding medium ball, the roundness of the ball is good, the labor force is saved, the efficiency is improved, and the cost is reduced.
